on style.xml, got definition:

<color name="transparente">#00ffffff</color> 

and code:

public class dialogos extends dialogfragment {     private static final string parametro_titulo = "titulo";     private static final string parametro_mensagem = "mensagem";     private static final string parametro_txt_btn_positivo = "txtbtnpositivo";     private static final string parametro_txt_btn_negativo = "txtbtnnegativo";      public dialogos(){     }      public static dialogos newinstance(int titulo, int mensagem, int txtbtnpositivo, int txtbtnnegativo) {         dialogos fragment = new dialogos();         bundle args = new bundle();          args.putint(parametro_titulo, titulo);         args.putint(parametro_mensagem, mensagem);         args.putint(parametro_txt_btn_positivo, txtbtnpositivo);         args.putint(parametro_txt_btn_negativo, txtbtnnegativo);          fragment.setarguments(args);          return fragment;     }      @override     public dialog oncreatedialog(bundle savedinstancestate) {         int titulo = getarguments().getint(parametro_titulo);         int mensagem = getarguments().getint(parametro_mensagem);         int txtbtnpositivo = getarguments().getint(parametro_txt_btn_positivo);         int txtbtnnegativo = getarguments().getint(parametro_txt_btn_negativo);          typeface fonte = typeface.createfromasset(getactivity().getassets(), "fonts/regencielightalt.ttf");          final alertdialog.builder builder = new alertdialog.builder(getactivity());          layoutinflater inflater = getactivity().getlayoutinflater();         view view = inflater.inflate(r.layout.mensagem_dialogo, null);         textview tvtitulo = (textview) view.findviewbyid(r.id.titulo_dialogo);         textview tvmensagem = (textview) view.findviewbyid(r.id.mensagem_dialogo);          tvtitulo.settypeface(fonte);         tvmensagem.settypeface(fonte);          if (titulo != 0)             tvtitulo.settext(titulo);          button btnpositivo = (button) view.findviewbyid(r.id.botaopositivo);         button btnnegativo = (button) view.findviewbyid(r.id.botaonegativo);          tvmensagem.settext(mensagem);          btnpositivo.settypeface(fonte);         btnnegativo.settypeface(fonte);          btnpositivo.settext(txtbtnpositivo);         btnnegativo.settext(txtbtnnegativo);          btnpositivo.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {             gettargetfragment().onactivityresult(gettargetrequestcode(), activity.result_ok, getactivity().getintent());             }         });          btnnegativo.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {             gettargetfragment().onactivityresult(gettargetrequestcode(), activity.result_canceled, getactivity().getintent());             }         });          builder.setview(view);          return builder.create();     } } 

the problem alertdialog builder not designing transparent dialog , , have black background theme it, instead use dialog create transparent theme instead.

sample:

    dialog alertdialog = new dialog(this);     alertdialog.requestwindowfeature(window.feature_no_title);     alertdialog.setcontentview(r.layout.tabs);     alertdialog.getwindow().setbackgrounddrawable(new colordrawable(android.graphics.color.transparent));     alertdialog.show(); 

using dialog not require theme manipulation transparent background easy.
